Hi i just got my xperia play and noticed that it is almost unusable when im charging, the keyboard will hit random keys i cant scroll from the main screen etc. But as soon as i pull the charger usb out it functions perfectly, anyone know whats up?
I've noticed something similar, the accuracy isn't as good when the charger is plugged it. Are you using it with the pad out or not? try with the pad out and see if that helps, otherwise it may be a hardware fault
I use it while it is charging all the time. It works perfectly.

I haven’t had any problems using mine while plugged in.
This is not that uncommon as one would think really. Capacitive touch screens may react different and most of all less accurate when plugged in to a charger. Try using a different wall socket when charging and you'll probably notice some difference to this behaviour.
A grounded wall socket is usually better than a non-grounded one.

Every time i charge my aria, while its plugged in to an AC charger, the screen seems buggy to me, the only way i can get it to work is if i put a finger on the metal part on top while im navigating, and even then it can do some funky stuff.
its like super sensitive or something.
and when i have it plugged into the computer, its even worse, completely unusable.
this happens all the time, no matter what rom i have on the phone.
its a pain, anyone else experiencing this?
never had anything like that happen.
I had this problem using an lg wall charger but not with the provided wall/usb chargers or a motorola car charger
Sent from my HTC Liberty using XDA App
strange, its happening on the oem chargers
This is happening to me too. Super sensitive keys, impossible to scroll. Happening to me on CM6, can't remember if it was same on Sense/Liberated
Same problem here with stock ROM, although only certain aftermarket chargers. The one that came in the box (as well as using USB from the PC) are fine. But they also charge much slower. I think the other chargers have a higher voltage (like 5v USB as compared to 3.3v). It's annoying for sure, but not a deal-breaker for me.
Oink!
It only happens to me when I use the aftermarket wall charger. I'm on liberated b003 rom.

hmmm, maybe ill go buy another oem charger, see if its a problem with the charger
happens to me on a wall charger/car charger set i bought on ebay or amazon...cant remember
oem charger is fine and so is any other cable plugged in to the pc to charge.
it's just that one damn wall charger that doesnt charge very fast anyway. just got it as a backup for at work.
I actually had this problem with my iphone 3gs and some charger i bought off of ebay. When the phone was plugged into it, the capacitive panel was all wonky and i couldn't use the phone. I guess it was a poorly designed charger.
Happens to me too across all ROMs using the oem charger. I don't have an after market to test with.
same is happening to me with a 3rd party microusb charger on my desire, if i try to pinch to zoom, while charging, the screen goes crazy
Ok, so I get to work and decide to plug in my phone from an old charger from another phone. I plug it in and all of a sudden, my touchscreen is WAY OFF. I hit the icons near the top and my middle icons light up.
I thought it was the phone, tried different settings, then ended up plugging in the native USB charger/cable....and all is fine.
Just in case any else runs into this issue, try the original charger.
Same thing happened to me on ny Captivate with a generic charger I purchased on Amazon.

That is a problem with the charger hitting a sensitive spot in the usb bus, this happened a lot with the hero as well when using an aftermarket charger. I messes up touch input and makes the phone unresponsive to touch altogether sometimes
Oh yeah, common issue - bad grounding I always suspected.
I've had the exact same issue. I've been using the generic charger that I used for my Pre, and the touchscreen goes crazy when it's plugged in.
It's kinda like an extra puzzle in the morning. Have to remember to unplug the phone before I can disable the alarm clock.
Here I thought I found something new....
Ah well...thanks guys/gals
I've looked everywhere. i promise i tried to search it first before asking here.

Every time my phone is plugged in, wall or computer...swype doesn't seem to process finger swyping correctly.
anyone know why this happens and how to possibly fix this?
Are you using a third party charger? If it's not sending out the right amount of electricity it could be interfering with the touch screen (which is conductive).
I've noticed this behavior sporadically as well, with both OEM and third party charging solutions, but never when charging via USB plugged into a computer, only from the wall.
I can only speculate, but perhaps I've got relatively "dirty" (unsteady) power in my apartment wall outlets, and it's resulting in voltages outside this device's tolerances.
I've noted only the touchscreen appears to become unresponsive, this doesn't seem to have any effect on the ability for the battery to charge up.
I have this issue too when charging off my inverter in my truck. I had this on my mytouch as well. I just figured it was from the unstable line voltage. I haven't noticed any other affects from it other than that.
Agree with the others. Bad charger.
I've been experiencing this issue with many different chargers.
I've tried wall and car chargers with dedicated cables and also the car and wall chargers which give you a usb port to plug into, with 2 different data cables.
Even though the issue occurs with different chargers, it bothers me the most when it's plugged into my computer. Having it plugged into my laptop is a lot more convenient for me charging-wise.
I have no problem with any other application. I play Angry birds and homerun battle 3d with zero issues in touch screen response.
master reset of the phone doesn't help. I honestly think it's possibly an issue with swype.
I notice I need to press the screen harder when plugged into the wall for swype to input correctly. The problem is the screen not swype. You just don't notice it with other apps because of the need for less precision.

It's not that. You know when your texting, the swype "trail" is smooth, when it's plugged in, the lines get jagged and the phone picks that up instead of my original input and trys to guess the word off of the jagged line.
This happens to my phone and I always assumed it was heat related. This does not happen to me with the original samsung charger but on my cheap ebay wall and vehicle charger it does. Samsung charger is .7 amps and the others are 1 amp.

When the phone is charging, and i try to use touch, i notice the input is jittery- try pulling down the notification bar on the top, and holding it half way down the screen and looking closely. Scroll with lists and hold your finger in once place - does the list jump around slightly?
Is it just me or everyone?
Maybe I should not use my blackberry charger at work! I will test with the samsung charger at home (the output voltage is the same as the samsung so it shouldnt matter!)
I feel you man! Had the exact same problem with the original Galaxy (i7500) - my unofficial charger made it impossible to type anything: heavy jitter.
Ccl: find a charger with the exact same specs...or just use the official one / or usb cable.
No problems here. typing this using swype While charging and its faultless!

Well it's better than my Desire which gives you a static charge or electric leak somewhere when charging and you touch the metal bezel.
i read something about this issue in the user manual, the PDF one somewhere in this forum
look it up, and read the battery or charging section
Have the same exact problem with my Original Galaxy S when using a "not-samsung" micro USB charger, with the obvious difference that my screen became completely unusable not just "jittery", it didn't respond to any touch when charging it with that charger.
Use official charger and it'll be fine !
Yup it is mentioned in the user manual, it said the touch screen may not function well due to an unstable power supply. I guess it applies to all touch screen phones.
thanks for the input guys and hopefully this will clear it up for anyone else confused by this.
Last question - am I damaging my phone by charging it on my blackberry charger?
Only one I have at work which is why I ask,
Thanks.
While I cannot confirm whether it will damage the SGS II or not, I can certainly say that when I used to use BB Chargers to charge my Motorola Razr among others that were Mini USB, they ended up ruining the battery life and giving me false readings about the percentage left.
Personaly I would not take the risk for my beloved 600€-phone

Yeah. But is the current the same? It may not be supply enough amperage for stability.

I dont know - I just tested and the same thing happens with my old Samsung Galaxy S 1 charger . hmm.
(my phone works just fine.(only while charging via pc). it does jitter when you charge it through mains.
voltage converter?
Since I live in the US and ordered a UK model, will i need a voltage converter + plug adapter for my charger or will a simple plug adapter work just fine?
This phone has capacitative touch screen, and I believe this works on the principle of changes in electric field upon bringing a conductor(read "finger") near the charged display. I suppose during the charging process the leaked current is interfering with this electric field causing those above mentioned problems. Might be substandard charging adapters?
Same problem on my Dell Streak! A good thing to test it is Swype! The line your finger makes when typing goes all over the place!

It'll charge over the usb lead from a PC or mains adapter just fine.
I always use pc to charge my phone is it ok ? will it be better charging from AC ?
have anyone got issues with S2 when plugged into power?
ie when I start recharging direct from 240V adapter, my S2 started getting VERY laggy and slow.
It immediately goes back to normal response when I unplug power.
I have never problem like you

Try using an alternative charger...probably your mains charger or the usb connector on the charger is damaged.
I'm pretty sure its a issue with the s/w as I have used the charger on another phone without any issue.
unless its one of the apps I'm using, not sure how to narrow it down.
mtrax...
I have the same issue.
You´re not alone...LOL
FYI the common issue I have when plugged in is that its not easy to unlock screen, takes me a 2-3 swipes to unlock screen and after that it seems that it ignores every other key press..
Any one reported this to Samsung? I will try to log a ticket to see what happens.
Try do a multi touch test while its plugged in see if the screens acting funny.
how do I do a multi-touch test?
what will that prove? as the screen works fine when unplugged.
I have the same issue but only when charging with the usb lead (with usb power adapter) instead of the standard mains charger. Think it might have stopped now that debugging is enabled and the Samsung kies screen doesn't come up when i connect the usb.

Took my phone 2 hours to charge from 36 % to 100 %
note this issue doesn't occur when charging via PC ONLY via 240V mains, but let me try with USB debugging on.
edit tried USB debbuging still has issue.
Note is the 240V USB cable different from a normal USB cable? ie perhaps the device thinks its a PC connection
the phone is laggy because of the electrical interference from a faulty charger or some other electrical equipment in the near vicinity...
Please note that actually the capacitive touchscreen becomes laggy not the applications/services...
keep it away from the electrical interference...use the samsung original charger..gud quality USB cable....and the issue will be gone... for sure
looks like its the charger, the A/C adapter I got with the phone was UK which is why I didn't use it to begin with, but tried the samsung one with a UK/AU adapter and its fine..
hmm who would have thought that was the issue...
interesting it didn't affect my other HTC phone.
Same issue here, but something special:
I ebayed another charger for my sgs2, original samsung one. Same serial number, same description, same style.. but i got the charging problem only with the new one.
With my original charger (the one, which was delivered with the phone) works fine. No slow and no lag.
The new one was about 5 euro, seems to be an original...
to demonstrate my point that its the electrical interference from the dodgy chargers onto the capacitive touchscreen... do this and report back...
plug the faulty charger onto the socket BUT DO NOT charge the phone with it...
keep the phone near to the charger wires etc....(not in charge)... you will see the screen lagging sometimes unresponsive...
now move the phone away ...it will work fine..
you can keep on using the dodgy chargers for charging...but use the phone only after it has been charged and is away from the charger...

I am not able to reproduce that with my original charger. There is no lag or any other problem. Switching to my second "original" (ebay 5 €uro) samsung charger leads me direct to the lag and your description. First i thought my second one is not an original one, but because of your description there seems to be a diffrent quality on the original charger depending on it production date.. unit.. charge.. or whatever.
I bought a sgs2 from the UK, and have a UK to AUS converter on the stock charger and I have no lag when it's charging or near chargers.
Sorry. Not a problem here. Writing now and plugged. Very responsive.

The electrical interference with the capacitive display is bullcrap since it needs electrical properties to respond. So it depends on whether your body has enough electrical properties.
So back to the point:
It is due to CPU reducing the clock speeds to prevent the phone from overheating as the battery itself produces enough heat anyway.
Many other people may not notice it since they may not perform intensive tasks while the phone is plugged in and the variation itself is also almost unnoticeable.
I have the same issue but as I said, it's almost unnoticeable to even bring it up in this forum. I haven't done any testing myself to prove this, but the same safety feature is implemented in most modern phones.
I have the same issue - I also had this issue with my Atrix.
